hitTestPoint on invisible sprite?

rrraptor

I have a container that have sprites in it, and I need to detect if sprite is clicked, BUT if parent is INVISIBLE then hitTestPoint still triggers.

Example code:

--[[ Sprite1 -> parent: stage ↳ Sprite2 -> parent: Sprite1 ↳ Sprite3 -> parent: Sprite2 ↳ Sprite4 -> parent: Sprite3 ↳ px -> parent: Sprite4 ]] local t = {} for i = 1,4 do local cont = Sprite.new() t[i] = cont if i > 1 then t[i-1]:addChild(cont) else stage:addChild(cont) end end   local px = Pixel.new(0,1,32,32) t[4]:addChild(px) t[1]:setVisible(false)   stage:addEventListener("mouseDown", function(e) print(px:hitTestPoint(e.x,e.y,true)) end)

According to the wiki the third parameter "shapeFlag" supposed to solve the problem but this did not happen.

shapeFlag: (bool) Take hidden, clipping/masking into consideration when testing hit point optional

So the questions are: Is it a bug? How to fix it?)

It is a bug, the code seems to check visibility only on the current sprite, not its parents. One more thing to fix

i thought that's intentional, heh.
meanwhile:

function Sprite.isVisibleRecursive( sprite ) if not stage:contains(sprite) then return false end local visible = false repeat visible = sprite:isVisible() sprite = sprite:getParent() until sprite == nil or visible == false return visible end

rrraptor

yeah, I did same thing

function Base:hitTestPoint(x,y,shapeFlag) local parent = self:getParent() while parent do if not parent:isVisible() then return false end parent = parent:getParent() end return Sprite.hitTestPoint(self,x,y,shapeFlag) end

Does anybody know if it's been fixed? I have tested but it doesn't seem to work for me.

Looks like (from the code) it hasn't. Doing it now.

thank you hgy29
